Abstract Biological control of Drosophila suzukii may be enhanced through adventive populations the figitid parasitoid Leptopilina japonica (Novković & Kimura) (Hymenoptera: Figitidae). This insect has expanded its range considerably but we have limited understanding phenology, wild host plant associations, and response to fruit crop management this parasitoid. To address these gaps, samples were collected in managed habitats across southern Michigan, placed on metal mesh a plastic container until insects emerged, when they captured identified. We selected yellow sticky traps based experiments compare trap types for capture D. L. japonica. Weekly checking resulted 2,108 2022 2023 yielding 7,598 specimens. Wasp detection started mid-July increased steadily mid-September, with activity declining into October. emerged from multiple species, highest yield both years blackberry (Rubus spp.), American black elderberry (Sambucus canadensis), pokeweed (Phytolacca americana) fruit. was much more abundant unmanaged organic blueberry plantings than commercial fields during berry ripening, sharp increase after pesticide applications ended. The methods described here facilitate widespread sampling parasitoids without needing daily collection insects. Our results highlight an updated method showing that established production regions persisting (Diptera: Drosophilidae) larvae berries plants ripen growing season.
